Honeywell TH115-AF-GA/U Radiant Heating 120/240V Programmable Thermostat with Floor Sensor and GFCI

Thermostat was a perfect replacement for my the one in my heated bathroom floor...easy to install and to program, what more could I want?

If you are reading this, you should be pretty familiar with your options. This unit allows for floor sensing and the modes allow you to heat to a targeted floor temperature, targeted air temperature, or a targeted air temperature while controlling the min and max floor temps. It also allows separate schedules each day with 4 settings per day. Things to know about this (if they matter to you): * You can use either 120 or 240v, depending on how you wire it. * The included instructions do NOT agree with the markings on the unit itself. Input/Output are different in the instructions versus the unit itself. I don't know if this is a typo or a translation problem. (I followed the unit markings and it seems to be working well.) * If you opt for a 24-hr (military/European style clock, you can only have CELSIUS temperatures. Otherwise you only get a 12-hr (AM/PM)/Fahrenheit display. * It does have a heat anticipator option if you want it either click on or off at a certain time or if you want it to decide when to turn on and off to reach the target temperature by a certain time. I like it and recommend it.

Easy to set up and get running right out of the box. Bright easy to read display. If you are replacing an older model thermostat, check the sensor loop resistnce of your sensor wire with an ohm meter. Mine read 17 ohms. This new model comes with a sensor wire that measures 12 ohms. If that's your case, and you decide to keep using your old sensor wire, you may need to up the temperature setting on this thermosat by a few degrees in order to compensate for the higher risistance in the sensor wire. I did that and it works fine.

We bought this product 17 months ago. I had reservations because I read that sometimes it fails after a year or so and I worried that returning or exchanging it would be an issue. I was right. This failed after 17 months. I tried to contact the 3rd party seller without success. I contacted Amazon support and they reminded me that I had purchased an extra warranty through Asurion. I contacted Asurion and they said the product was still under manufacturer warranty so I needed to contact Honeywell. Honeywell has TERRIBLE customer support. I was trying to deal with all of this on a Saturday so the warranty support department was closed. I called the customer support line from the website and they said the wait on hold would be "over and hour'. I made a batch of cookies while I waited 1 1/2 hours before giving up. I will call the original warranty support number on Monday during work hours to hopefully figure out how to return this product. This was a pretty good product until last week. I'm not saying you should not buy it. Just get it from a brick and mortar store so you can easily return it if it fails.

My bathroom floor heater stopped working. I replaced the 10 year old thermostat with this one. My floor is now ready for when it gets cold this winter. It was easy to wire up, it was compatible with the floor heat and the existing in floor sensor. It could have been a little bit cheaper but it works great.

Replacement was an Exact match, easy install. Programming was the hardest part until I went to youtube. Do yourself a a favor go straight to youtube for programming.

Delivered early and well. Have not installed yet, but instructions look easy to follow.

Stuffing all the wires into a conventional switch box is a challenge. Although I rated it as 4 stars for ease of use - it's because you have so many choices in heating times. You must read the enclosed manual! I bought this as a replacement for a unit that kept complaining it was shorting out (GFCI kicked in). I was pretty sure that there was not an electrical problem - I took several readings of resistances and could find no underlying cause. I know it was a bit of a gamble - but ripping up the floor was an option of last resort. New one is installed and working fine. If you are not comfortable working on 120V electrical lines then get a reputable electrician to install it.

This product works GREAT. The thermostat that I had for my bathroom floor had issues after 23 years and we could not find a new one locally. Went on Amazon and got exactly what I needed. It was installed and my floor immediately started to warm up. Highly recommended

After reading other reviews on this listing from other people who had an older one that needed replacing, I felt comfortable enough to give this a try even though it seems hard to nail down the exact same part number. My previous model had PB112B-120GB stenciled inside. New one says PB112D-GA. Based on other feedback I wondered if I might have to add a resistor inline with my already installed floor probe but I tried it without and it shows the correct temp so all seems well. It does look like there is a difference in the GFCI rating with the old stating "15mA GFCI" and the new one stating "Class A GFCI, 5mA". But it works and the old one had failed stuck with a GFCI warning so who knows, maybe this one is more correct for my home. Or it is just working better now but will be more sensitive? I don't know. I am just happy to have a warm floor again.

This item was a direct replacement for a unit that had died. A slight difference is this unit is it's a 5ma GFI unit whereas the original was a 15ma GFI unit; I was fully aware when I ordered it and considered it irrelevant to me. For all intents and purposes the old and new unit were identical...except in the load and source diagram on the back of the unit: They were reversed! This is the reason I rated it only 3 stars. I caught this detail while replacing it and wired it correctly as per the diagram before enabling the breaker. This unit works perfectly.

bad

Package arrived, does not say Honeywell, Box says Aube, was not happy at first, but googled “Aube” and apparently Honeywell bought Aube on 2004. I already have one of these Honeywell thermostats in an other room in the the house, and it does look identical.
